Mass of 1 hazelnut= 125/90=1.388888889  g

Calories per g= 630/100= 6.3 calories per g

Calories per hazelnut= 6.3*1.388888889 =8.75 g

Write a power that has a value greater than 340 and less 345
valina [46]

For this case we must write a power between (340,345)

We chose 343.

We divide the number until we get an exact division:

\frac {343} {2} = 171.5\\\frac {343} {3} = 114.3\\\frac {343} {4} = 85.75\\\frac {343} {5} = 68.6\\\frac {343} {6} = 57.17\\\frac {343} {7} = 49\\

So we have:

7 ^ n = 343\\n = 3

So, the power is:

7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343

ANswer:

7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343

oksano4ka [1.4K]

Answer:

It is m(x) = 20,000(0.97)^x.

Step-by-step explanation:

After 1990, each year has (100-3) = 97% ( or 0.97) of visitors that it had the previous year.

So m(x) = 20,000(0.97)^x   (answer).

A salad made such that the difference between twice the ounces of greens and the ounces of carrots is at least 3. Also, the sum
kap26 [50]

Answer:

3rd graph down

Step-by-step explanation:

greens are x and carrots are y in my equations

2x - y >= 3

x + 2y < 4

The first equation is solid and will highlight everything to the right of it because it is a >

the second is dashed and will highlight everything to the left of it because it is a <

the only 2 graphs that show this are 1 and 3

looking at the points you can see that the points for the solid line are both the same so ignore those and go to the dashed lined ones.

on the first graph the points are (0,4)

plugging those into our equation gives us 0 + 2*4 <4

or 8<4 which doesnt make sense making 3 the correct graph

(sorry my answer wasnt posting so i had to start over and make it less detailed, but comment if you need any explanation)
